I bought this engine brand new from Singapore when I was messing with alternative fuel and found a source for ethanol. One day there was a discussion if an OS .55 engine can run without muffler pressure. I had bought a methanol fuel head for the .55 AX so I could run this engine on methanol when I wanted to. So I took the engine and ran it on the test stand for a few minutes without muffler pressure. It ran just fine. I oiled it and put it away and I have not run it since. Here is a link to the video of the engine running on methanol. https://youtu.be/ivmIT8pk7q8 The engine comes with the original ethanol head (the combustion chamber is smaller) and I will include the methanol head . It comes with an OS 40J carburetor and when I compare the carburetor to a "regular" OS 40J carburetor for methanol I noticed the venturi diameter is smaller. The ethanol head is threaded for an ethanol plug which is included. The methanol head takes standard glow plug. It comes with a muffler. Both the carburetor and muffler has minor discoloration from sitting in the box with oil.
